This research explores how cognitive load influences the ability to distinguish between real and fake news. In an era of constant information exposure, individuals often process news while engaged in other cognitively demanding tasks. This study examines how cognitive burden affects classification accuracy, confidence levels, and response time in news assessment tasks. Using an experimental approach, participants were assigned varying levels of cognitive load while evaluating news articles. The results provide insights into the impact of cognitive effort on susceptibility to misinformation and offer recommendations for enhancing critical news consumption.
